FEED BOX.

Application led May 1, 1923. Serial No. 635,991.

To aZZ 'whom t may concern Be it known that we, Luo SELINGER and JACOBSELINGER, subjects of the King of Great Britain, both of the town ofLajord, in the Province of Saskatchewan, Canada, have jointly inventedcertain new and useful Improvements in Feed Boxes, of which thefollowing is the specification.

The invention relates to improvements in feed boxes and particularly toa feed box for feeding grain, such as oats, to horses and an object ofthe invention is to provide a feed box which will operate to feed aylimitedv and predetermined quantity of grain to the animal, therebycausing him to properly masticate the food.

A further object of the invention is to construct the appliance so thatit can be readily regulated to feed a greater or less amount of food asdesired and also to construct the saine so that it can be readily setand controlled.

A further object is to construct an appliance which can be utilized tocontrol the feed of several animals by simply extending the devicethrough the duplication of certain parts.

A further object is to construct the device so that it can bemanufactured at reasonable cost and can be relied upon to operatesatisfactorily.

`With the above more important objects in view the invention consistsessentially in the arrangement and construction of parts hereinaftermore particularly described and later pointed out in the appendedclaims, reference being had to the accompanying drawing in which Fig. 1is a front view of the device.

Fig. 2 is an end view thereof.

Fig. 7 is an enlarged detailed vertical sectional view through theneedle valve, the c lindrical casing and other parts associatectherewith.

ln the drawing like characters of referon the stub shaft. Vare providedwith engaging clutch members ence indicate corresponding parts in theseveral figures.

The box 1 is substantially rectangular and is provided at the top with ahinged cover or door 2 and at one end with a hinged door 3, the door 2permitting off the placing of the grain, such as oats, into the boX andthe door 3 permitting of inspection of the operating parts. The box isinteriorly dividedby two partitions L1 and 5 to provide two feedcompartments 6 and 7 and a mechanism compartment 8, the lattercompartment being at the end having the door 8. The bottom of the boxunderneath the compartments 6 and 7 is open. A rotatably mounted shaft 9is mounted in the lower part of the boi; and centrally crosses thecompartments 6 and 7, the said shaft being carried by suitable bearingssecured to the partitions and to one end of the box. .On this shaft wemount a pair of similar feeders 10 and 11, the said feeders turning withthe shaft and each presenting end discs 12 and 13, between which welocate a plurality of suitably spaced vanes or wings 14 radiating fromthe shaft.

By this construction we provide a plurality of similar .more or lessV-shaped feed pockets 15. Ve provide each feed compartment with a moreor less hopper shaped bottom 16 and these hopper bottoinswfeed the grainplaced in the compartments into the pockets of the feeders as the samearel rotated, as later described. l

The mechanism for controlling and rotating the shaft 9 is contained inthe compartment 8 and comprises the parts now Y described.

The shaft 9 is projected through the partition 5 andhas the projectedend fitted .with a pinion 17v which meshes with .a gear `wheel 18, thegear wheel being rotatably mounted on a stub shaft 2O secured to thepartition 5. A pinion 21 is also mounted The pinionV and gear 19, saidmembers being held into engagement by a. pressure-spring V19. The pinion21 meshes continuously with a vertically disposed rack bar 22 which hasthe ends thereof provided with sleeves 23 and 24; slidably mounted on aguide bar .25 permanently secured to the box. The sleeve 24 is suppliedwith an outstanding arm 26, the purpose of which will be laterdescribed.

nected to the arm 26, such as by screwing the upper end of the tube intothe arm. The lower end of the tube passes slidably through 11' the cap28, a suitable bushing being-therein provided and the end thereof is`contracted to provide a tapering valve seat which communicates with aduct 3l leading to the interior ofthe cylinder 27. A needle valve 32 adjoins the seat, the stem of the valve extending upwardly'through the tubeand having the upper end thereof screw threading through the arm 2G andprovided with an adjustingwheel Obviously by manipulating the wheell 33one can seat the valve orY open the same a greater or less amount.

Above the` valve the tube 29" is provided withA an outlet .opening 34,the arrangement being'such th'atupon the valve' being opened there is athrough passage up theV duct 31 andv outv the. opening rhe lower end ofthe rod 29: is fitted with a plunger orA piston operating within thecylinder, the piston lbeing beneath the opening 34 and beneath K thepiston is'looated a disc valve 36 whi'chvis adapted to operate within ahousing 37 formed as an4 extension' on the underside of theA piston.YEntry vopenings 38 are' `pror' vided in the housing beneath the discvalve and further outlet openings 39' are; provided in the side ofthehousing above the disc valve. lt will be observed (..secv .Figure 7)that there are ports or openings 40 through theJ plunger", theseconnecting the upper part ot' the casing 27' with the chamber locatedabove the disc valve.

The cylindrical casing 27 contains a regulating liquid, such as oil,indicated at 41, it being desirable that the same be non-freezing. Theplunger is adapted tok move up and down within the cylindrical casingand it will be apparent that if theneedle valve be opened'v andtheplunger forced down the oil i-n the cylindrical casing' will` `flowlthrough the opening 31 and out the opening 34 under the pressure of thepiston andfurther that thel fiow of oi-ll will bey absolutely controlledby the setting of the needle valve. The pressure ofthe oil at theunderside of the piston will also act through rthe open-V ings' 38 toforce up the disc valve so that the said disc valvev will close theopenings 3:9 and also those 40. ln the up movement of the piston thepressure ofthe oil, which is then vabove the piston, will operatethrough the openings to force down the disc valve and consequentlypermit the oil to escape past the piston out the openings 39.

According to the abo-ve arrangement it is possible for lus to regulatethe speed at which.theipiston goes down by setting the needle valve andit is also possible to more or less quickly raise the piston as in theup movement thereof the oil has a= more` or less free passage throughthe plunger from the top side to the underside.

lIn the compartment 8 we locate a cross shaft 42 which carries `aconical drum 43 and is adapted to be rotated by a coil spring 44, thespring having one'end' fixed tothe vside of! the box and the otherendattached to the drum which is in turn secured to the shaft.

To the drum we attach one end of a cable, cord orl such like 45, theother end of which passes upwardly over suitable pulleys 4G and47providedat the top ofthe box and then extends downwardly and outthrough. the bottomof thebox. This cord `is fastened at 48 tothe upper.sleeve 24.

According to this arrangement it. will be obvious that by pulling d'ownon the end of the cord' extending fromthe box, the sleeve is raised and'conseqllently the rack bar kand at the same time turn the drum in amanner to windy upthespring 44. The yparts are so shown in Figure3`whichis the Aset po sition of the device.

.Having broughtthve parts to 'this position one places the feed", suchas oats, in the feed compartments 6 and 7 and regulates the needle valveto control the flow of oil. Obviously the springk44 will act 'to pulldown the rack bar which operates to force down the plunger and' at thesame time slowly rotate the feeders, the speedof rotation dependingentirely on the setting ofthe needle valve. 4 As' the feedersrotate theygradually fill with the oats or other g 'ains and expel the same at theunderside of the box through the open bottom thereof. The expelled andfalling canbe directed to a box to which the ani-mals have access.

Obviously, by' utilizing tlellector plates,

the present appliance will feed two annuals.

B'y increasing the 'numberzof feeders and by providing suitable delectorplates, chutes,

spouts or `othermeans ive-,can feed any numl ber of animals' with theone device.

After the spring 44has uncoiled the device' is reset by pullingtheextending end of the cord.A T his turns the drum ,and winds thespring and duringv this movement the clutch member 19' disengages sothat the l. In combination, a compartment for the reception of feed,said compartment having a discharge opening in the bottom thereof, ashaft crossing the lower part of the compartment, a feeder rotating withthe shaft and presenting a plurality of radially disposed pockets, saidpockets being adapted to successively register with the outlet openingin the rotation of the feeder with the shaft, a stub shaft adjoining theformer shaft, a gear wheel mounted on the.stub shaft, a pinion meshingwith the gear wheel and mounted on the former shaft., a pinion rotatablymounted on 'the stub shaft, engaging clutch members carried by the gearwheel and latter pinion, a spring normally maintaining the clutchmembers engaged, a slidably mounted rack bar engaging with the latterpinion, a cross shaft, a winding drum rotatably mounted on the crossshaft, a spring associated with the drum, a pulling line connected tothe drum and to one end of the rack and adapted when pulled in onedirection to shift the rack and wind the spring, and means for governingthe speed of travel of the rack bar under the influence of the woundspring.
